The Diary can reveal how the former Fair City star made sure it was an affair to remember after booking into the exclusive Mount Juliet Estate in Kilkenny.
The 28-year-old actress - who's marrying hotelier John Burke next month - was joined by her actress friend Aoibheann McCaul, and her sister Ailbhe, who's also acting as her bridesmaid.
Castleknock native Aoibhin and her gal pals indulged in some relaxing spa treatments at the hotel before taking part in the old-fashioned country pursuit of falconry.
They then headed into Kilkenny city to enjoy some cocktails before hitting the tiles.
Glamorous Aoibhin recently played the part of Gwendoline Fairfax in The Gate's production of The Importance of Being Earnest, which later went on tour to South Carolina.
But she'll be putting work to one side for a while as she concentrates on her wedding.
The couple will be getting married in a small country church in the West of Ireland followed by a reception in the Armada Hotel, at Spanish Point, in Co Clare.
She and John will also go long-haul for their honeymoon - they have booked a once-in-a-lifetime holiday in Myanmar.
The pair, who have been dating for over six years, got engaged on Aoibhin's 27th birthday in June 2015 while enjoying a walk on the scenic Cliffs of Moher.
Far from having a big lavish party to mark their wedding, Aoibhin said she was keen on having a simple, intimate affair - "just a bit of a party with my nearest and dearest", as she put it.
She and her other half won't be signing up for any glossy magazine deals for their special day and they want to keep it all about their happy union.
"There's a lot of pressure on people now to put on productions, and I'm kind of allergic to that," she said.
"It's more about the people and the place and the day itself than the glitz and the glam. I hope it'll be a sentimental day," she said.
"It's really important for me to have my family involved in aspects of the ceremony and the music, my family are all very musical.
"All those little things are important," she added.
The star played the part of Neasa Dillon in RTE's Fair City before quitting the soap to pursue other acting projects.
